📢 Announcements

Developers!

We are writing to announce two API deprecations, both of which will be removed by June 18, 2026:

A small removal of the account.balances field → you should be using account.balancesV2 going forward. More information on this can be found here.
Deprecating Organization Verifications in favor of Compliance Reviews (see more on that below)

We wanted to reach out to let you know that our organization verification KYC onboarding endpoints (this and this) are now deprecated. We have released new Compliance Review endpoints for general access and ask that you transition over to this flow as soon as possible.

Compliance Reviews get you:

Pre-submission validations applied to attestation submission so you and your user can catch user-input problems before submitting to our compliance team, avoiding unnecessary back and forth after submission.
Pave the way for what we are calling “Programmatic RFIs” — this API will soon faciliate the back and forth between our compliance team and you/your users, so no one needs to rely on pesky emails

When do I need to transition by?

We will be shutting off the legacy organization verification endpoint EOD on June 17, 2026, so all requests made to this endpoint will fail as of June 18, 2026.

How do I migrate to Compliance Reviews?

The new migration guides for using the new flow can be found here

Where can I find more information on Compliance Reviews?

You can find everything you need regarding Compliance Reviews as a concept here

🌐 New Routes

USD wire and ACH payouts directly from USD fiat balances — previously USD fiat balances could only pay out to blockchain destinations. You can now send wire/ACH payouts directly from a USD fiat balance.
Inbound USDC on Solana — your Mural Accounts can now receive USDC deposits on Solana, in addition to the existing supported chains.

⭐ Enhancements

Compliance Reviews — individualTaxInfo is now its own attestation.
Compliance Reviews — nationality is now optional on the KYC Light attestation.
USD Payin methods in the Accounts API — the DBA ("doing business as") name is now used as the beneficiary on the payin method when set, falling back to the legal name otherwise.

🐛 Bug Fixes

Ramp-fee input validation now returns 400 instead of 500 for invalid input.
Improved post-fee minimum enforcement and terminal-failure handling on payout and deposit flows
Sandbox — simulated WIRE payins now include an IMAD so senderMetadata renders correctly
